Counterclaim in Procedural Law

The scope of this study is the Counterclaim in Procedural Law. Although the doctrine consists of different definitions for the counterclaim, generally it can be defined as a claim brought by a defendant against a plaintiff in an instant (original) case in the same court under conditions including defendant's claim of set-off and deduction or conditions related to the instant case. While trying to explain this issue, doctrine opinions and the decisions of the Court of Cassation were also utilized. The present study is composed of four main sections. The types of lawsuits are examined in a general manner in the first section. Commonly, the concept and significance of counterclaim, its conditions, unacceptable counterclaim and differences of the counterclaim from similar institutions are examined in detail in the second section under the title of counterclaim. The principles and consequences of the counterclaim and the litigation costs in the counterclaim and the problem of application in terms of the time were attempted to be examined in detail in the third section. Finally, in the fourth section, the legal remedies were tried to be examined in detail in some other proceedings such as administrative law and arbitration.
